Product description
With the ESERA 1-Wire Multisensor Pro II you have
acquired a professional and highly accurate
Multisensor. Due to the new technology of the ESERA
1-Wire Multisensor PRO sensors, the accuracy of the
humidity readings is on average 200 - 300% higher
compared to most sensors on the market.
Due to the use of high quality internal sensors with
12Bit resolution, the 1-Wire Multisensor Pro II provides
very accurate values for temperature, relative humidity
and air quality. In addition, the evaluation of the
delivered measured values is enormously simplified.
The 1-Wire Multisensor Pro II enables simple climate
monitoring of rooms and buildings.
The Multisensor is installed in a shapely surface-
mounted housing and fits harmoniously into modern
furnished living and business rooms. Inside view sensor
Due to the generous ventilation openings, the 1-Wire Multisensor Pro II detects the climate conditions in
rooms very directly and quickly.
For all types of radiator and heating controls, an accurate temperature sensor such as the one installed in
the Multisensor is an important actual value transmitter.
The Air Humidity Sensor provides information about the humidity conditions in the living space and can be
used to prevent mold growth.
With the help of the Air Quality Sensor a good statement about the current air quality and hint for ventilation
can be given. It is also the optimal sensor for controlling a ventilation system.
In combination with 1-Wire ESERA Switching modules / binary outputs a very effective and energy-saving
heating control (single room control) is possible.
The 1-Wire Multisensor Pro II is intended for use in normal living spaces. For outdoor use and in damp
rooms, such as sauna, steam bath or winter garden, a suitable sensor is available via the ESERA website.
The 1-Wire Multisensor Pro II has a short warm-up time of a few minutes for the air quality value.
The electrical connection to the 1-Wire Bus system of the 1-Wire Multisensor Pro II is made with screw
terminals and can be operated in standard mode (3 cables for ground, data and 5V).
Each 1-Wire Multisensor Pro II has an individual serial number.

Auto-E-Connect® System
With the launch of the ECO Controller, the ESERA Auto-E-Connect® 1-Wire Plug and Play system for the
1-Wire bus is now introduced and supported.
This now enables fully automatic configurations of 1-Wire devices (sensors and actuators) on the 1-Wire bus.
It is optimized for commercial and industrial applications and enables significant added value beyond sensor
and chip data.
The Auto-E-Connect function is built up in three levels. Currently there are Level I, Level II and Level III
available.
Please refer to the "Technical data" to find out which Auto-E-Connect functionality this sensor supports.
With Auto-E-Connect Level III, fully automatic configurations of the 1-Wire devices on the
1-Wire Bus are possible. It is optimized for industrial and IoT applications and enables significant added
value beyond sensor and chip data.
Note
